Forming apparatus and forming method

A forming apparatus configured to form a metal pipe, comprising:

• a heating unit configured to heat a metal pipe material;
• a gas supply unit configured to supply gas into a heated metal pipe material, thereby expanding so as to expand the metal pipe material;
• a die configured to form the metal pipe through contact with the expanded metal pipe material;
• a cooling unit configured to cool the metal pipe by a cooling medium;
• and
• a control unit configured to control the die, the gas supply unit, and the cooling unit,
• wherein the control unit is configured to:
• control the die such that a state where the die in contact with the metal pipe is maintained for a predetermined time such that the die cools the metal pipe;
• control the die to separate the die from the metal pipe after cooling the metal pipe by the die;
• and
• control the cooling unit to supply the metal pipe with the cooling medium after separating the metal pipe from the die.
